Tech 7 said: (quoted from post at 13:14:13 11/18/13) Tx Jim might post a page from the parts catalog to help us out, but until then I would check up in the steering column above the hand pump. There is a thrust bearing in the steering shaft that will disintegrate and make the steering tough. I have seen this a few times.

I know that you're trying to get me reprimanded for posting too many parts photos. :wink: This post was edited by Tx Jim at 11:45:15 11/18/13.

I just found out from the owner of the tractor that they have put 3 complete steering columns on it with no change,they all acted the same way. So i dont think its anything to do with the column and I put my valve with all my fittings on it this morning and that helped alot. It had several places that acted like it was sticking when you was turning the steering wheel. Now with my valve on the tractor it is no longer doing the sticking and is a 100% better it just doesnt steer as easy as it should especially when you force the steering wheel. Wondering what you guys think about the back pressure piston in the front steering motor? Is there any way to check for that? Or what would be any symptoms for the back pressure piston failure?

Some times #30 check valve leaks pressure past and gives a bit of a Hydraulic lock,this would give you the easy steer as you start up then getting harder afterwards..and the thrust bearing in the column needs looked at when you have it apart like Tech7 stated..
